<p>A climbing feature device for installation in or on a climbing surface comprises a plurality of faces having different climbing features thereon, the climbing device being operable, when installed, to present different selectable ones of its faces at a climbing surface. The device may comprise a rotary hexagonal drum having different climbing features on at least some of its six surfaces, which may be presented at the climbing surface as required. On the hexagonal drum, one face could be blank in order to provide no climbing feature at that particular location on the climbing wall if required, with different climbing features on the other surfaces. It is advantageous if the device is designed so that each climbing feature, when presented, is extremely rigidly fixed so that there is no danger to the climber. Further as regards safety, the device is preferably designed to be failsafe, so that it is maintained in a rigidly fixed position should the device fail. <IMAGE></p> |
